Samsung and SK Hynix Unveil $870 Billion Push to Expand AI and Chip Manufacturing in South Korea
South Korea is preparing for one of the most ambitious semiconductor buildouts the world has ever seen. Samsung Electronics and SK Hynix are moving ahead with a massive long-term investment plan worth about 1,350 trillion won, or roughly $870 billion, aimed at expanding chip manufacturing, AI infrastructure, and next-generation memory production across the country.
The 10-year plan is designed to strengthen South Korea’s position in the global semiconductor race as demand for AI chips, DRAM, NAND flash, and advanced manufacturing capacity continues to surge. With global competition intensifying against major players such as TSMC and Intel, Samsung and SK Hynix are accelerating their efforts to secure a larger share of the future chip market.
A major part of the investment will go toward building new semiconductor fabrication plants in the South and North Chungcheong regions. Over the next decade, Samsung and SK Hynix are expected to construct four to five advanced chip fabs in these areas, turning the region into a major semiconductor manufacturing hub.
SK Hynix is reportedly planning to invest around 400 trillion won into its Cheongju production facility, while another 100 trillion won is expected to support a new production cluster in the southwest region. The Chungcheong region itself is also set to contribute around 100 trillion won to help build out the semiconductor ecosystem.
The expansion is not limited to chip fabs. The plan also includes major investments in AI data centers, battery production, display manufacturing, and advanced semiconductor equipment. This includes tools for EUV lithography, etching, photomasks, chemical mechanical polishing, and deposition, all of which are critical for producing cutting-edge semiconductors.
One of the biggest goals of the project is to increase memory chip output. South Korea wants to double its DRAM production capacity within five years while also expanding NAND flash manufacturing. This comes at a time when the industry is facing tight supply conditions, especially as artificial intelligence systems require more high-bandwidth memory and larger storage capacity.
The government-backed strategy is also speeding up construction timelines. Facilities that were previously expected to be completed sometime after 2040 are now being targeted for completion around 2033. That acceleration highlights how urgently South Korea is responding to rising AI computing demand and the growing need for advanced memory chips.
The plan could significantly reshape the global memory market. Samsung and SK Hynix are already two of the world’s most important memory manufacturers, and this new wave of investment could further strengthen their dominance in DRAM and NAND flash. At the same time, the expanded production capacity may increase pressure on competitors across Asia and beyond.
For South Korea, this is more than just an industrial expansion. It is a national strategy to secure leadership in next-generation computing, artificial intelligence, and advanced semiconductor manufacturing. By combining government support with the scale and experience of Samsung and SK Hynix, the country is positioning itself as a key force in the future of AI hardware and memory technology.
If successful, the investment could help ease global memory shortages, support the rapid growth of AI data centers, and make South Korea an even more powerful player in the global chip supply chain. The scale of the commitment shows that Samsung and SK Hynix are not simply preparing for the next semiconductor cycle; they are working to define it.
